Description
Technical Field
[0001] The utility model relates to the field of deformed steel bars, in particular to a welding device for deformed steel bars. Background Technique
[0002] Deformed steel bars, also known as deformed reinforcing bars, are steel products widely used in the construction industry. They are steel bars with spiral ribs, which can increase the bonding force between the steel bars and concrete, thereby improving the stability and bearing capacity of the overall structure.
[0003] Welding of deformed steel bars is a method of connecting two sections of deformed steel bars through welding technology. It has wide applications in construction, bridges, shipbuilding, and various metal structure projects. Through the welding of deformed steel bars, the stability and bearing capacity of the structure can be effectively improved, while reducing material waste and increasing material utilization rate. The welded deformed steel bars can form a continuous and integral structure, which helps to resist external forces and enhance the seismic performance of the structure. In addition, the welding of deformed steel bars can also reduce the gaps at the joints, reduce the risk of corrosion, and thus extend the service life of the structure.
[0004] In the actual industrial production process, most of the welding of deformed steel bars uses manual arc welding or semi-automatic gas shielded welding. Manual electric welding results in low welding efficiency of deformed steel bars, is prone to welding defects, and cannot control the uniformity of the welding torch, resulting in fluctuations in welding quality. Moreover, during the welding process, due to the experience of the welding master, it is difficult to ensure the consistency and accuracy of welding.
[0005] Therefore, a welding device for deformed steel bars is proposed here to solve the above problems. Content of the Utility Model
